Abstract The Iona Skeleton Coast Trans-Frontier Conservation Area (TFCA), straddling the border between Angola and Namibia, has suffered through decades of civil war and poaching. While this history has been detrimental to the community of large mammals in the TFCA, data collected on the mammal populations are insufficient to enable effective management. Survey methods such as aerial counts and community-based monitoring have various shortcomings. Therefore camera trapping, which has become ...
Abstract Land cover refers to the observed vegetation, structures, or other features that cover the land such as closed forests, open forest, woodland, grasslands, bushland, and settlements. Land cover change is one of the serious threats to the forests and woodlands of Namibia, and it is mainly triggered by forest resource utilization and conversion to agriculture by local communities. As one of the mechanisms to control land cover change, Namibia introduced the Community Forests (CF) progra...
ABSTRACT Zimbabwe is preparing itself for 2015 dead line for the elimination of methyl bromide through adoption of floating tray system, metham sodium, basamid and other related tobacco nursery chemicals. In an effort to complement this government initiative to fulfil Montreal protocol, a research was carried out at Kushinga Phikelela National Farmer Training College, in Marondera during the 2014-2015 tobacco farming season with intention to evaluate the effect of an on farm composted tea tre...
ABSTRACT Root Knot Nematodes are one of the major economically important pests of tomato (Lycopersicon esculentum L) in many regions of the world including Zimbabwe, with Meloidogyne javanica being considered the most destructive. Recent prohibition of main soil chemical fumigants for the control of Meloidogyne javanica has prompted for the search of other alternatives to manage root knot nematodes. A greenhouse experiment was carried out to evaluate the effects of aqueous plant extracts on (...
Abstract Human existence generates massive amount of waste. These wastes are usually dumped at disposal sites especially in developing countries due to lack of landfills. As a result of continuous waste dumping, soils in disposal sites have become sinks of toxic heavy metals. Oshakati disposal site is open and all waste from the town irrespective of the source get dumped at the site. The scoping assessment which was done at the site in 2018 found high levels of heavy metals way above the stan...
ABSTRACT Farmer irrigation practices have contributed to reduction of irrigable area from 14.6ha to 9.6 ha at Mutorahuku irrigation scheme due to water loss and shortages in the scheme. A study carried out at the scheme showed that farmer irrigation practices also contribute much to water loss and shortages. Infield canal tail end losses were measured with a collecting bucket and a stop watch. Using the t test results showed that there is a significant difference between the observed and expe...
ABSTRACT Use of Tobacco (Nicotiana tabacum L.) resistant varieties in plant parasitic nematode management programs has been increasing in developing countries including Zimbabwe. Resistant varieties provide both economic and sustainable benefits for smallholder farmers who dominate the tobacco industry in Zimbabwe and produce their tobacco under continuous cultivation. A field trial was conducted at the Tobacco Research Board (TRB) during the 2014-2015 growing season to evaluate the effects o...
Abstract A study to investigate the prevalence and associated risk factors was done in Murehwa district; Zimbabwe. The research was aimed at determining the prevalence of the disease and also determining the associated risk factors as determinants of the disease. The study was done by using questioners to randomly selected farmers who had reported the disease to the Veterinary Services. A total of 378 cattle were examined in the dry and the wet season. Statistical analysis was performed using...
i ABSTRACT Land use changes have been occurring as a result of human uses for developmental purposes. These changes will certainly have a negative influence on the hydrological characteristics of catchments, thereby inducing an increase in surface runoff, soil erosion and sediment inputs. In the year 2000, Rio Tinto discovered kimberlite diamonds in Murowa, Zvishavane. This discovery led to the relocation of 142 families to Shashe resettlement block in Masvingo Province near Mashava. The area...
ABSTRACT The main aim of the study was to assess the factors that affect goat production. The study was concerned with the analysis of socio-economic factors affecting goat production; with special reference to Zhombe district. Zhombe is a communal settlement area that that is found in the midlands province of Zimbabwe. It consists of 31 wards but the research was done in ward 12 which is south east of Gokwe. Data collection was done through structured questionnaire administered to 40 respond...
ABSTRACT Root-knot nematodes (RKNs) are of economic importance in tobacco production especially the specie M. javanica with increased virulence. Over the past decades chemical control has been effective in the management of M. javanica, but due to its negative impacts to the environment, among all management measures use of resistant varieties has an increased efficiency. This study sought to evaluate the resistance of Kutsaga Research Board bred varieties which are T 66, T 71, T 64, T 29 and...
Abstract Title: Investigating the Potential of Moringa Oleifera for Agribusiness Development and Rural Youths’ Self-Employment in Livingstone Rural Areas Moringa oleifera is a nutritious vegetable tree with a variety of potential uses as almost every part of the tree can be used. Moringa oleifera is very useful as an alley crop in the agro-forestry industry. It is useful not only for human beings but also for animals and also in various industrial applications. Besides Moringa oleifera bein...
Abstract Vegetable Amaranth (A. cruentus) is a promising C4 crop for semi- arid regions due to its nutritive value, medicinal property and ornamental for beautifying gardens . It is widely grown in the tropics and is one of the most important leafy vegetables in the lowlands of Africa, South America and Asia. Little knowledge is known on its Nitrogen requirement, that is why this experiment was conducted to fill in that gap. A field study was conducted in Nyanga which is a high rainfall area ...

ABSTRACT Fire is an ecological disturbance that may kill or topkill woody plants and control the biomass of woody species in disturbance prone areas, thus maintaining the co-existence of trees and grasses in savanna ecosystems. Relatively recently, savannas have been altered worldwide by a phenomenon known as bush encroachment, which is the suppression of grasses by woody species due to the increase in woody biomass. Terminalia sericea is a woody encroaching species which occurs in woodland s...
